Product Description

High Quality Factory Sale Insulating Rock Wool Board

Rock Wool Board is a high-performance, inorganic insulation material manufactured from natural volcanic rock, typically basalt or diabase, and recycled slag. The raw materials are melted at extreme temperatures (approximately 1,500°C) and then spun into fine fibers using a centrifugal process. These fibers are then bonded with a thermosetting resin and formed into rigid or semi-rigid boards.
External thermal insulation rock wool board is specially designed for external thermal insulation composite system.It has the quality of high tensile strength, good dimensional stability, water repellent, low water absorption etc. We have three different products to meet customer's needs i.e. LR140, LR160, LR180.

Why Choose Our Products?

  • Excellent Thermal Insulation:Low thermal conductivity (typically 0.035-0.045 W/m·K) helps reduce energy consumption in buildings and industrial applications.
  • Superior Fire Resistance:Rock wool is non-combustible (Class A1 or A2 according to European standards). It can withstand temperatures up to 1,000°C without melting, acting as an effective fire barrier.
  • Acoustic Performance:The fibrous structure provides excellent sound absorption, making it ideal for noise reduction in walls, ceilings, and floors.

Primary Applications

  • This product is specially designed for external thermal insulation composite system.
  • Suitable for dry hanging stone curtain wall, aluminum-plastic composite plate curtain wall, aluminum panel curtain wall insulation system etc.
  • Used as fire barrier for external thermal insulation composite system of non-class A fire classification insulation.
  • Other places that has high requirement for fire-proof, thermal insulation, water-proof etc.

Frequently Asked Questions (FAQ)

Q1: Do rock wool boards contain hazardous substances like formaldehyde or crystalline silica?

A: Our standard rock wool boards are formaldehyde-free and comply with international health standards, such as the EU CE mark and US EPA regulations. Although trace amounts of crystalline silica may be naturally present, our products meet OEQ Class I (Ecological Quality Class) standards and are classified as non-carcinogenic under EU Regulation (EC) No. 1272/2008.

Q2: What is the maximum service temperature of your rock wool boards?

A: Our standard boards have a continuous operating temperature range of 750°C (1382°F) to 1000°C (1832°F); depending on density (e.g., 120–200 kg/m³), they can withstand short-term peak temperatures of up to 1200°C (2192°F). For higher temperature requirements, please inquire about our ceramic fiber alternatives.

Q3: What densities are available for your rock wool boards?

A: Typical densities range from 60 kg/m³ (lightweight, for sound or thermal insulation backing layers) to 200 kg/m³ (high-strength, for furnace walls subject to mechanical loads). Higher density offers superior erosion resistance but relatively lower thermal shock resistance. We can provide recommendations based on your specific application.
